In this paper, the research object is 2.75Ah lithium ion battery. Peak current can be directly characterized by the peak power, so we use HPPC, optimized JEVS and constant current charge/discharge to test the battery peak current between 5%SOC and 95%SOC at different duration in 10℃, 25℃ and 45℃.
Although there have been many studies on state estimation of lithium-ion batteries (LIBs), aging and temperature variation are seldom considered in peak power prediction during the whole life of the battery.
The applicability of the optimized JEVS test method in the study of the peak power test of lithium ion batteries is analyzed based on the experimental results of different test methods. 2.

In the high SOC region, current serves as the dominant factor limiting the peak power capability of batteries, where the peak discharge current is held at the maximum discharge current (i.e., current constraint for discharge), and the terminal voltage continues to decline throughout the window, yet it does not reach the lower cut-off threshold.
To fill this gap, this paper aims to propose an adaptive peak power prediction method for power lithium-ion batteries considering temperature and aging is proposed.
In order to accurately predict the power of lithium-ion batteries online, this study uses the VFF-RLS algorithm and EKF algorithm to jointly estimate the parameters and SOC of the battery. Based on the results of parameter identification and SOC estimation, the battery power prediction under multiple constraint conditions is carried out.
